Embodiment

[0040] Embodiment: clarification, filtration in draft beer brewing process

[0041] Filtration process:

[0042]The beer is fermented in the yeast tank 1, and the liquid level of the fermentation tank is controlled by the yeast tank level gauge 8. After the fermentation is completed, the discharge valve 21 of the yeast tank and the valve 23 of the feed pipe are opened, and the operating pressure difference is set to 0.2 MPa through the centrifugal pump 7. The flow rate of the membrane surface is 3m / s. Part of it enters the membrane separation device 2. After separation, the dope passes through the heat exchanger 6 to keep the temperature at 0-4°C and returns to the yeast tank. The other part passes through the feed pipe circulation valve 19 and separates from the membrane. The feed circulation valve 24 of the device passes through the heat exchanger 6 to keep the temperature at 0-4°C and returns to the yeast tank again. The clear liquid enters the beer tank 4 through the beer ...

Abstract

The invention relates to an inorganic ceramic membrane device for applying to clear and filter draught beer and a method thereof. The device structurally comprises a yeast tank, a series of separator main bodies, a ceramic membrane separation element, a backlash tank, a cleaning tank and a pump. The pump is utilized to pump the draught beer in the yeast tank in the inorganic ceramic membrane separation device; the draught beer is filtered through the ceramic membrane separation element to remove saccharomycetes and microorganism such as bacteria in the beer and a colloid deposit sediment generated by cooling flocculation; the clear beer is separated and sent into a subsequent manufacturing procedure; and one part of a mother solution containing yeast returns to the yeast tank, and the other part of the mother solution is circularly filtered through a circulating pump. The inorganic ceramic membrane device provided by the invention adopts the inorganic ceramic membrane as a filtering element, so that the inorganic ceramic membrane device can carry out steam sterilization and disinfection.

Description

technical field [0001] The invention relates to a device and a method, in particular to an inorganic ceramic membrane device and method for clarification and filtration of draft beer, which adopts an inorganic ceramic membrane as a filter element and can be sterilized and sterilized by steam. Background technique [0002] Beer is a carbon dioxide-containing, low-alcohol drink made from malt, rice, hops and water as the main raw materials and fermented by brewer's yeast. It contains a variety of essential amino acids and rich vitamins. It has high calorific value and is easily digested and absorbed by the human body. It is known as "liquid bread". In recent years, beer has become a kind of mass consumer goods in our country, and the beer industry in our country has also developed rapidly. [0003] During the storage of draft beer, microorganisms cause spoilage and protein causes turbidity. For a long time, diatomite filtration and pasteurization methods have been widely use...
